Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

slidev-transitions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

  • Emphasizing slide changes
  • Matching presentation themes
  • Creating unique visual effects

Setting Transitions

Global Transition (Frontmatter)

---
transition: slide-left
---

Applied to all slides in the presentation.

Per-Slide Transition

---
transition: fade
---

# This slide fades in

---
transition: slide-up
---

# This slide slides up

Inline with Separator

# Slide 1

---
transition: zoom
---

# Slide 2 (zooms in)

Built-in Transitions

Fade Transitions

Name Effect
fade Simple fade in/out
fade-out Fade out, then appear
---
transition: fade
---

Slide Transitions

Name Effect
slide-left New slide enters from right
slide-right New slide enters from left
slide-up New slide enters from bottom
slide-down New slide enters from top
---
transition: slide-left
---

View Transition

Uses the modern View Transitions API:

---
transition: view-transition
---

Note: Requires browser support for View Transitions API.

Directional Transitions

Forward/Backward Different

Use | to separate forward and backward transitions:

---
transition: slide-left | slide-right
---
  • Going forward: slides left
  • Going backward: slides right

Common Patterns

# Natural slide direction
---
transition: slide-left | slide-right
---

# Vertical navigation
---
transition: slide-up | slide-down
---

# Fade forward, slide back
---
transition: fade | slide-right
---
